ENAM key terms

National Medical Examination of Ecuador, a mandatory licensing test that Ecuadorian medical graduates and foreign-trained physicians must pass to practice medicine in the country.

Official blueprint document that lists the content domains, subareas, and the number of items each area contributes to the examination, guiding candidates' study planning.

Formal authorization granted by health authorities that allows a physician to legally practice medicine in Ecuador after meeting academic and examination requirements.

Governing health council in Ecuador that oversees professional credentialing and coordinates with universities and the Ministry of Public Health on licensing matters.

Relative weight or percentage of exam items assigned to each content domain, used to allocate study time proportionally to how heavily each area is tested.

First level of contact between individuals and the health system, delivering preventive, curative, and rehabilitative care in the community; a major focus of Ecuadorian medical training.

Structured record of a patient's symptoms, medical history, physical findings, and management plan, forming the basis for diagnosis and continuity of care.

Systematic interview of the patient to gather the chief complaint, present illness, past medical history, medications, allergies, and family and social background.

Structured physical assessment using inspection, palpation, percussion, and auscultation to detect signs of disease and support clinical diagnosis.

Study of the signs and symptoms of disease and the techniques used to elicit them, central to clinical reasoning and diagnostic accuracy.

Reasoned list of possible conditions that could explain a patient's presentation, ranked and progressively narrowed through history, examination, and targeted testing.

Cognitive process of integrating patient data with medical knowledge to reach a diagnosis and treatment plan, often tested through clinical vignettes.

Objective finding detected by the clinician during examination, such as a murmur or rash, as opposed to a symptom reported by the patient.

Activities that enable people to increase control over and improve their health, including education, healthy public policy, and community empowerment strategies.

Measures taken before disease occurs to reduce incidence, such as vaccination, health education, and risk-factor modification in healthy populations.

Early detection and prompt treatment of disease at a presymptomatic or early stage, exemplified by screening programs such as mammography or Pap smears.

Systematic testing of asymptomatic individuals to identify those at sufficient risk of a specific disorder to warrant further investigation or intervention.

Proportion of people with the disease who correctly test positive; a highly sensitive test is useful for ruling out disease when negative.

Proportion of people without the disease who correctly test negative; a highly specific test is useful for confirming disease when positive.

Probability that a positive or negative test result correctly reflects the presence or absence of disease, dependent on test characteristics and disease prevalence.

Proportion of a population with a given condition at a specified point or period in time, influencing predictive values of diagnostic tests.

Number of new cases of a disease arising in a population over a defined period, reflecting risk and used to study etiology and prevention.

Ratio of disease incidence in exposed versus unexposed groups, estimating how strongly an exposure is associated with developing the outcome.

Ratio of the odds of exposure among cases to the odds among controls, commonly used to estimate association in case-control studies.

Observational design comparing people with a disease to similar people without it, looking backward at prior exposures; efficient for rare outcomes.

Observational design that follows groups defined by exposure status over time to measure incidence of outcomes and estimate relative risk.

Range of values around an estimate that is likely to contain the true population value with a stated probability, usually 95 percent.

Result unlikely to have occurred by chance alone under the null hypothesis, conventionally judged by a p value below 0.05.

What the body does to a drug over time, encompassing absorption, distribution, metabolism, and elimination, and determining dosing intervals and steady-state levels.

What a drug does to the body, including receptor interactions, dose-response relationships, potency, efficacy, and mechanisms of therapeutic and adverse effects.

Fraction of an administered dose of drug that reaches systemic circulation unchanged, influenced by route, formulation, and first-pass metabolism.

Time required for plasma concentration of a drug to fall by half, guiding dosing frequency and time to reach steady state.

Any harmful or unintended response to a medication occurring at normal doses, requiring recognition, reporting, and sometimes discontinuation of the drug.

Alteration of a drug's effect by another drug, food, or substance, changing its absorption, metabolism, or pharmacologic action and potentially causing harm.

Drug that kills or inhibits the growth of bacteria, selected according to suspected organism, site of infection, and local resistance patterns.

Ability of microorganisms to survive exposure to drugs that would normally kill them, driven largely by inappropriate or excessive antibiotic use and requiring stewardship.

Range of microorganisms against which an antibiotic is active, classified as narrow or broad and informing empirical therapy choices.

Set of practices, barriers, and procedures designed to protect patients and health workers from exposure to infectious agents and hazardous materials in clinical settings.

Infection acquired by a patient during the process of care in a hospital or other facility, often preventable through hand hygiene and device management.

Voluntary agreement by a competent patient to a medical intervention after receiving adequate information about benefits, risks, and alternatives, documented in the record.

Discipline analyzing moral questions in medicine and research, organized around principles of autonomy, beneficence, nonmaleficence, and justice.

Duty of health professionals to protect patient information from unauthorized disclosure, a cornerstone of trust and a legal obligation in clinical practice.
